What are the steps to draw a Free-Body Diagram (FBD)?
- Draw the object as a point or simple shape. 2. Draw arrows (vectors) to represent each force, with the tail on the object. 3. Label each force.
How do you analyze an Atwood's Machine?
Analyze the whole system or individual masses by applying Newton's Second Law to each mass and considering the tension in the string.
Define Dynamics.
The study of forces and their effect on motion.
What is Weight (Force of Gravity)?
The force pulling an object down due to gravity; calculated as .
Define Normal Force.
The force exerted by a surface on an object, perpendicular to the surface.
What is Tension?
The pulling force exerted by a string or rope.
Define Friction.
A force that opposes motion between surfaces.
What is a system?
The collection of objects being studied.
Define Gravitational Field.
The region around a massive object where other massive objects experience gravitational force.
What is Inertia?
The tendency of an object to resist changes in its state of motion.
Define Net Force.
The vector sum of all forces acting on an object.

How do you relate force to motion using Newton's Second Law?
- Identify all forces acting on the object. 2. Calculate the net force (vector sum of all forces). 3. Apply the equation to find the acceleration.
